Application filed December 3, 1918. Serial No. 80,=37.

To all whom tt may concern.'

Be it known that l, JOHANN G. WALL- MANN, a citizen of the Unite States, residing at the city of Galrland, in the .county of Alameda and State of California, have invented certain new and useful lmprove' ments in Liquid-Fuel Controls for Motor- Cars, of which the following is a specification.

My invention relates to fuel-saving devices for motor-cars. i

The object of my invention is to provide a device for motor-cars which is particularly designed to etliect a saving in liquid fuel as used therein, and also to give the engine therein greater power and speed and a lower temperature, while permitting the use of a heavier gasolene 'than usually used. The device is also designed to relieve to a great extent tbe wear and tear on brakes in bill Work; automatically adjusting the proper -mixture for ascending and descending carbureter adjustment.

My invention consists in tbe combination ln the drawing l indicates a cylinder. havlug a` lll-shaped slot l. A slidable cylinder 5 liavinfif a V-shaped slot 2 is containedin said cylinder Il. A fixed cylinder 6 is secured or screwed-into the manifold 35, and

said cylinder has an oblong slot 3 as shown. A regulating control lever 1 4, manually operated, is pivoted on the steeringpost of an automobile' or other suitable conveyance, where it is in reach ol? the driver of tbe con-v voyance. A. guide pin 7 is fixed in the end Wall lof cylinder (i as shown.

u 8 represents a wire, preferably of steel, and 9 is a guide tube containing said wire. A guide tube l1 contains a. Wire 17, preferably of steel, liXed at its upper end as shown. A suitable bracket is shown at 1:2. l5 contains diapliragmsl separated and secured as shown.' A vessel 19 is provided with la cover having a plug 24, and a pipe 18 is secured in said cover and leads from said vessel upwardly into casing 15 and thence at right angles therein. Mercury 21 is contained in'said vessel 19 for its operation, and a. pipe 29 leads from the base of said vessel 19 linto the base of a similar vessel 2O having a cover and also provided with a plug 24, the last mentioned. vessel lalso containing mercury 21. A hand-valve 22 is secured in pipe 29 for regulating the ilow' of mercury through' said pipe. Diaphragme 1G by their casing are preferably fixed to the dashboard of a car. The mercury controlling device is allixed to tlie car 1n a suitable place which is convenient to the operator,

while not encroaching on space to be used,

and should be on the level when-the car is on level ground, the pipe 18 being then connected from the 'diaphragme to the mercury pressure control beneath as shown.

In'tbe operation, on moving lever 14 back-h Wardly, the wire 8 in the guide tube 9 forces cylinder 5 in the same direction, closing port 30. The car is now ready to start as it al- ,lows a ricli mixture to enter the engine cylinders from the carbureter by Way of the manifold. While the car is moving on level ground and tbe operator wislies to get theA A casing Willgradually open port 30, allowing air to pass through port 30 into the manifold by Way of cylinder 6-tliis air mixing with the Laas. By the gradual opening of the port 30 the operator can easily ascertain by the running of the engine if he bas the right proportion of liquidfuel for smooth and.v

economical running of, the car on 'level roads. Thus the mixture is adjusted for level roads and tbe weather, and the lever does not require handling again'as the other cending a grado the mercury will flow from the vessel 20 into the vessel 19, vessel 20 being 1n the forward part of the motor-car and higher than vessel 19 causes the Iner- 1o cury to seek its level by flowing through tube 29 and valve 92 to cylinder 19; the mercury entering the vessel 19 compresses tue air in its upper part, such compressed air passing by the tube 18 to the diaphragms i 1G, which causes them to expand forwardly in their guide casing l5. 'l`he forward movement of the diaphragms causes the wire l? to bc`moved forwardly in the guide tube ll, and which in turn causes the mov- 20 able cylinder l to be pushed forwardly thereby closing the open port 30. in this Yay a rich mixture of fuel is allowed to enter the cylinders and which is necessary for hard elfort in climbing hills. Onreacln ing the top of a hill and level ground the diaphragms in the car are automatically adjustcd to their normal position by the mercury iowing backwardly from vessel 19 to Q0, relieving the air pressure in them, and

this condition opens'the port 30 again as it stood before ascent of the hill and allows "the proper mixture for work on level ground. 'On descending a grade the vessel lf) being the higher of said vessels, causes the mercury to flow into vessel 20 and causes a partial vacuum to be formed in the upper part of cylinder i9. This partialvacuum causes the 'diaphragme to contact, thereby causing the movable cylinder to be carried 40 bacliwardly and thereby opening the port 30. The steeper the grade the larger the port required.. Such opening of the port allows a great amount of air to enter 'the manifold and to be taken into the cylinders by the suctionof the engine. New by clos.

ing the throttle of the carbureter the operan tor of the carV can allow the engine to go down the grade'on compression, saving wear on the brakes at the same time'cooling 'the engine by the contact of cool air.

'lhe hand valve 22 is intended to be used to close the tube in which it is located by permitting no mercury to flow therein. ln this way the operator can shut ed the apparatus .if he not desire to use it.
